1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

China's High-speed railway (HSR) network had experienced rapid expansion during 2009 to 2013, and how the HSR expansion affects China's economy has been considerable concerned by both policymakers and researchers. Using firm-level data, this study accessed the effects of HSR on productivity distribution and resource misallocation among manufacturing firms. Incorporating difference in difference idea into a multilevel model, the results suggest significant misallocation rectifying effect of HSR at firm level. This effect is stronger for capital-intensive firms. City-specific analysis indicates that the effects of HSR on firm-level resource misallocation varies with city size, and firms grouped in small cities gain more misallocation rectification than those grouped in big and medium cities. Market potential, which is an important way through which the HSR affects efficient allocation of production resources, is found boost the marginal effect of HSR by reducing labor market segmentation and increasing agglomeration.
